Specific Heat Capacity and Latent Heat Questions - GCSE standard
Q4. When a cyclist uses the brakes, the bicycle slows down.
This causes the temperature of the brake pads to increase by 50 °C.
The mass of the brake pads is 40 g.
Given that the specific heat capacity of the material of the brake pads is 480 J/kg °C. Calculate the change in thermal energy of the brake pads.
How is the internal energy of the particles in the brake pads affected by the increase in temperature?
